A dynamic phonological model derived from the intonational analysis of a jargon aphasic patient

This study is a detailed phonological and intonational analysis of one subject's jargon productions. The cohesiveness and complexity of the intonation patterns and appropriateness of the gestures lead to the hypothesis that the jargon productions are due to phonological problems as opposed to semantic or syntactic problems. A psycholinguistic model containing a dynamic phonological component is hypothesized to account for this subject's jargon.     

Relationships and Emotional Experience in a Process of Gay Identity Development: A Case-Study Based on Personal Construct Theory

A case-study of gay identity development is presented based on Kelly's personal construct theory. The subject is a married man in his early thirties. Repertory grid technique is used to investigate the subject's construing of his relationships with gay men, and Kelly's account of emotion in terms of constructs of transition is used in analysing the emotional dimensions of the subject's experience. Three dimensions of interpersonal construing emerged from the grid analysis: emotional impact, negative affect and friendship. Five aspects of the subject's emotional experience are discussed: aggression, threat, anxiety, hostility and guilt. Some implications of the study for counselling are outlined, its limitations noted, and possible avenues for further research identified. It is argued that the study serves to illustrate the value of Kelly's perspective in understanding the interpersonal and emotional dimensions of gay identity development.     

Human motor responses to simultaneous aversive stimulation and failure on a valued task

The effects of presentation of an aversive stimulus and simultaneous failure on a bogus intelligence test upon a subject's aggressive reactions were studied. The subject's fist clenching was used as an indicator of aggression. Four conditions, generated by the combinations of two kinds of stimulus delivered to the subjects (aversive or nonaversive) and two outcomes of the task (failure or success), were investigated. 20 female and 20 male students (ages: 17-34 years) were instructed, upon the reception of an aversive or nonaversive acoustic signal, to press with the right hand a device that displayed a slide. Each slide presented an item from an intelligence test, to which the subjects were either allowed to answer successfully (success) or not (failure). Failure increased the subject's autonomic arousal, as measured by photoplethysmographic sensors, in all stimulation conditions, but only the condition with aversive stimulation increased the speed of clenching. This was interpreted as indicating subject's tendencies to aggression. These results are discussed in relation to the effects of frustration.     

The fall of fantasies: a Lacanian reading of lack

The purpose of this article is to explain to a non-Lacanian audience the broad philosophical foundations of Lacanian theory, particularly the relationship that Lacan draws between the human subject's ontological lack and his or her creative capacities. In an effort to explain Lacan's distaste for psychoanalytic approaches aimed at strengthening the ego, the article outlines the manner in which Lacan connects ego-driven fantasies to the constriction of the subject's psychic world. Lacan suggests that narcissistic fantasies are misleadingly seductive because they-in occluding the internal rifts and antagonisms of the subject's being-alleviate his or her anxieties about the contingent basis of existence. However, the illusory sense of plenitude and self-presence that such fantasies provide prevents the subject from effectively discerning the "truth" of his or her desire, thereby holding him or her captive in socially conventional psychic paradigms. In consequence, it is only the fall of the subject's most cherished fantasies that empowers him or her to pursue a degree of subjective singularity. The article also considers the clinical implications of Lacan's theory of lack, including the ways in which the analyst's lack enhances the patient's capacity to claim an increasingly autonomous and multidimensional mode of encountering the world.     

A COGNITIVE THEORY OF PSYCHOPHYSICS. II

The fundamental premise of this paper is that subjects code information in such a way that a variety of psychophysical functions can be obtained with the same stimulus attributes. Four terms must be defined in order to understand psychophysical equations. These terms are: (1) The subject's perceptual channel capacity, (2) the subject's cognitive channel capacity, (3) the experimenter's measure of stimulus information, and (4) the context variables associated with the psychophysical procedure.     

Racial Stereotypes: Measurement Variables and the Stereotype-Attitude Relationship

The widely used paradigm developed by Katz and Braly (1933) for the assessment of "stereotypes" has been criticized because of the ambiguity of the subject's task. In the present study, 2 alternate sets of instructions were used, attempting to make the subject's task more clearcut. Traits attributed to each of 5 ethnic groups were virtually identical to those given under the instructional format usually utilized in such studies. When subjects were asked to list the trait-attributions most commonly made by "others" in our society to each of the ethnic groups, responses concerning Negroes were considerably different from subjects' own attributions to Negroes. This own-others difference was not evident for the other 4 ethnic groups rated. Racial attitude was significantly related to attribution for 5 of the 17 traits attributed to blacks by over 10% of the subjects, when subjects were giving their own views. The degree to which a subject's attributions to Negroes agreed with those of the sample as a whole was not related to his racial attitude. However, the degree to which a subject's attributions to Negroes agreed with those seen as most commonly attributed by "others" in our society was positively related to racial prejudice. The implications of these findings for common conceptualizations of stereotype are discussed.     

Justified Judging

Traditional approaches to epistemology have sought, unsuccessfully, to define knowledge in terms of justification. I follow Timothy Williamson in arguing that this is misconceived and that we should take knowledge as our fundamental epistemological notion. We can then characterise justification as a certain sort of approximation to knowledge. A judgement is justified if and only if the reason (if there is one) for a failure to know is to be found outside the subject's mental states; that is, justified judging is possible knowing (where one world accessible from another if and only if they are identical with regard to a subject's antecedent mental states and judgement forming processes). This view is explained and defended.     

Unequal reinforcer magnitudes and relative preference for cooperation in the dyad

College-student subjects, who were paired with a confederate, chose to respond either independently or cooperatively for money reinforcers. The subject's relative preference for cooperation was assessed by a procedure (analogous to the psychophysical method of limits) in which response choice was monitored as reinforcer magnitude for one response mode was systematically varied while the other remained constant. Relative preference for cooperation was assessed when the confederate's payoff for cooperation was greater than the subject's (Experiment I) and when the confederate's payoff for independent responding was less than the subject's (Experiment II). For some subjects, changes in the confederate's reinforcer magnitudes resulted in shifts in relative preference for cooperation, which reduced the earnings differences, even though these preference shifts reduced the subject's absolute earnings. For those subjects for whom within-dyad differences in reinforcer magnitude produced no effect, a changeover button was introduced that allowed the subject to eliminate the payoff difference without reducing her own earnings; some subjects used this changeover button to eliminate earnings differences. Thus, the behavior of subjects varied, in part, as a function of reinforcer magnitudes provided for the confederate.     

The rubber hand illusion: sensitivity and reference frame for body ownership

When subjects view stimulation of a rubber hand while feeling congruent stimulation of their own hand, they may come to feel that the rubber hand is part of their own body. This illusion of body ownership is termed 'Rubber Hand Illusion' (RHI). We investigated sensitivity of RHI to spatial mismatches between visual and somatic experience. We compared the effects of spatial mismatch between the stimulation of the two hands, and equivalent mismatches between the postures of the two hands. We created the mismatch either by adjusting stimulation or posture of the subject's hand, or, in a separate group of subjects, by adjusting stimulation or posture of the rubber hand. The matching processes underlying body ownership were asymmetrical. The illusion survived small changes in the subject's hand posture, but disappeared when the same posture transformations were applied to the rubber hand. Mismatch between the stimulation delivered to the subject's hand and the rubber hand abolished the illusion. The combination of these two situations is of particular interest. When the subject's hand posture was slightly different from the rubber hand posture, the RHI remained as long as stimulation of the two hands was congruent in a hand-centred spatial reference frame, even though the altered posture of the subject's hand meant that stimulation was incongruent in external space. Conversely, the RHI was reduced when the stimulation was incongruent in hand-centred space but congruent in external space. We conclude that the visual-tactile correlation that causes the RHI is computed within a hand-centred frame of reference, which is updated with changes in body posture. Current sensory evidence about what is 'me' is interpreted with respect to a prior mental body representation.     

A new experimental method to identify the process of logical reasoning

Abstract: A new method to identify the process of logical reasoning is presented. In spite of its indispensability and importance, we have had few methods to identify a subject's reasoning process, except that of using verbal protocol data. In this paper, for the purpose of objective identification of the reasoning process, we propose a new method to obtain the subject's reasoning process, in terms of a resolution tree for a task of which the logical structure can be written by first-order predicate logic. The results of an experiment using this method are presented. They revealed some interesting features of human reasoning such as, large differences between subjects, remarkable parallel processes, and the existence of subgoals for each subject.     

Validation of two devices for evaluation of human psychomotor performance

The Pursuit Meter III (PM III) and the Simultaneous Hand and Foot Tracking (SHAFT) task are microcomputer-based devices for the evaluation of human psychomotor performance. Both devices are pursuit-tracking tasks. The primary task (PM III) requires a subject superimpose a line over a computer-generated sine wave. The computer wave is black and the subject's wave is red. The vertical position of the subject's wave is determined by a joystick controller. The SHAFT adds a second simultaneous tracking task (FTT) that is operated by means of a foot control. Ten naive subjects performed either device for 5 sessions/day over a three-day period. Each session consisted of 5 sweeps of the sine wave pattern. Mean performance on both tasks generally improved over the assessment period, and differential stability was reached within 10 sweeps for each device.     

Hemisphere differences in the mood state-dependent effect for recognition of emotional faces

Forty subjects viewed 10 pictures of facial expressions of emotion while they experienced a happy mood and 10 pictures while they experienced a sad mood. Later, while re-experiencing either a happy or sad mood, they were tested for recognition of these 20 target pictures intermixed with 20 distractors. Recognition of the 10 pictures seen earlier in a disparate mood was impaired significantly when they were presented at testing to the right hemisphere, but not when presented to the left. The right hemisphere appears to store the subject's mood as an integral part of a memory representation for an emotionally expressive face. When that face is presented at testing to the right hemisphere, recognition depends on whether the subject's test mood matches the mood stored in the representation. In contrast, the left hemisphere appears to store the subject's mood separately from encoded visual information about a face, and so recognition of a face presented at testing to the left hemisphere is unaffected by changes in mood.     

On the nature of the oceanic experience

It is postulated that consciousness is not simply an organ of perception, but that it possesses a structure, or organization, despite its enormous fluidity. In support of these views, the oceanic experience is explored. It demonstrates the impact, on this state of consciousness, of the subject's values and culture. Like the oceanic experience, every state of consciousness--what is in awareness at any given time--is a complex phenomenon that derives from all aspects of the psyche, including the subject's value system and the influences of his culture.     

Content, Rationality and Mental Causation

In this paper I will address the question of rationalizing mental causation which is involved in the processes of epistemic justification. The main problem concerning mental causation consists in the apparent incompatibility of the three following claims: (i) the subject's mental states (in particular his belief states) are realized by neural states of the subject's brain; (ii) the justifying character of belief transition consists in the fact that there are certain broadly logical relations between the contents of the relevant beliefs; and (iii) all generations of neural states are, at bottom, governed by the purely physical laws. I try to reconciliate the physical necessity of the neural states generation with the logical rationality of the belief transition. Surprisingly enough, it will turn out that, in a sense, each thinking subject is logically perfect. However, in another sense we are exactly as fallible and irrational as our common-sense tells us.This revised version was published online in October 2005 with corrections to the Cover Date.     

Interpersonal aggression as a function of subject's sex, subject's sex role identification, opponent's sex, and degree of provocation.

Ninety-five undergraduates served as subjects in an experiment where they could administer electric shock to an opponent and receive the same from an opponent. The independent variables were subject's sex, subject's sex role identification (as measured by the Bem Sex Role Inventory), opponent's sex, as well as degree of provocation from the opponent. Aggression was defined as level of shock chosen by the subject for the opponent. The results indicated that masculine subjects facing a male opponent were more aggressive than individuals of other sex role identifications whether or not they were provoked. It was also found that masculine males were more aggressive than other males or anyof the females. Furthermore, opponent's sex influenced the males' aggressiveness but had no effect on the degree of aggression in females. Finally, aggression increased in all subjects following increases in provocation. The results are discussed in terms of their implications for pyschological androgyny.     

ON QUALITATIVE CHANGES IN THE RETENTION OF FORMS

An experiment was performed to test the following prediction: If a pattern is learned in terms of 'schema with correction', and the subject's conception of the figural schema is changed during the retention interval, the 'memory' of the pattern will change correspondingly. Following the repeated presentation of a pattern S , and the memorization of a related pattern A , patterns deviating from S more and more in a predetermined direction were interpolated. This led to a highly significant systematic error of the predicted kind in the subject's performance when he subsequently was given a recognition test for A.     

Psychoanalysis: the transformation of the subject by the spoken word

Psychoanalysis recruits the power of the spoken word to modify the subject's relationship with his or her own unconscious psychic processes. It helps the analysand to reclaim for his or her words the psychic integrity that was lost or never achieved due to the power of defensive dissociation and repression. The psychoanalytic dialogue and the working through mediated by it lead to the elaboration of self-narratives and interpretive understandings, which contribute to the transformation of the subject's self-experience. Such transformation is conditioned by earlier integration of experiences of satisfaction in the context of bodily dialogues and speech with primary objects.     

Neurogenic cluttering

A case of acquired symptomatic cluttering in a 61-year-old patient with documented cortical, subcortical, cerebellar, and medulla lesions is presented. The subject's communication-related behaviors are described, and a comparison is made between this case, idiopathic cluttering, and the few cases of acquired symptomatic cluttering that have been reported     

Individual differences in game motivation as moderators of preprogrammed strategy effects in prisoner's dilemma.

The impact of three programmed strategies (tit-for-tat, 100% cooperation, and 100% defection) on cooperation level in the Prisoner's Dilemma game is examined as a function of the subject's motivational orientation (cooperative, competitive, or individualistic). Motivational orientation was assessed on the basis of each subject's choices across four classes of decomposed games. Following this assessment, subject's played 30 trials of Prisoner's dilemma in matrix form against one of the above-mentioned strategies. Results were wholly consistent with predictions, showing that (a) cooperatively oriented subjects cooperate with a tit-for-tat and a 100% cooperative strategy, but defect against a 100% defecting strategy, (b) competitive subjects defect against all three strategies; and (c) individualistic subjects defect against both 100% cooperative and 100% defective strategies, but they cooperate with a tit-for-tat strategy. It appears reasonable to conclude that the outcomes of a Prisoner's Dilemma have affectively different meaning (i.e., values) for subjects of differing orientations, and that subjects of all three orientations adopt strategies that effectively maximize their particular type of reward in the game.
